A new instrument is developed to display the spatial variation of microcircular flow using a laser speckle image sensing. The system consists of laser diode, linear image sensor, signal analyzer with 16bits microprocessor and colorgraphic display. Optional functions to show the rapid temporal variation of skin blood flow are demonstrated with much faster response time than the current laser flow monitor. For faster data acquisition within one second, a two-dimensional image sensor is introduced, aiming at the blood flow analyses through an endoscope and a slit lamp.
